Small cell neuroendocrine tumor of the bladder is a rare tumor characterized by poor differentiation and high aggressiveness. Very few cases worldwide have been reported till date. Recent literature shows equivalent survival data for localized disease treated with chemoradiotherapy combined with either bladder sparing surgery or radical cystectomy. We report a case of small cell neuroendocrine carcinoma of the bladder diagnosed after transurethral resection of bladder tumor, then followed by adjuvant chemotherapy for six cycles and awaiting radical cystectomy.

Breast cancer remains the leading cause of mortality among women with cancer. This article delves into the intricate relationship between breast cancer and cancer stem cells (CSCs), emphasizing advanced methods for their identification and isolation. The key isolation techniques, such as the mammosphere formation assay, surface marker identification, Side Population assay, and Aldehyde Dehydrogenase assay, are critically examined.

Background Aims: Patients with hepatocellular carcinoma (HCC) meeting UNOS-downstaging (DS) criteria have excellent post-liver transplantation (LT) outcomes. Studies on HCC beyond UNOS-DS criteria ("All-comers" (AC)) have been limited by small sample size and short follow-up time, prompting this analysis.
Approach Results: 326 patients meeting UNOS-DS and 190 meeting AC criteria from 9 LT centers across 5 UNOS regions were enrolled from 2015 to 2023 and prospectively followed.

This study aimed to evaluate the efficacy of pyrotinib, an orally administered small molecule tyrosine kinase inhibitor, combined with neoadjuvant chemotherapy in treating patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Pyrotinib works by inhibiting the HER2 signaling pathway, thereby preventing tumor cell growth. This single-arm clinical trial aimed to assess the total pathological complete response (tpCR; ypT0/is and ypN0) rate as the primary endpoint.

Lysine demethylases (KDMs) catalyze the oxidative removal of the methyl group from histones using earth-abundant iron and the metabolite 2-oxoglutarate (2OG). KDMs have emerged as master regulators of eukaryotic gene expression and are novel drug targets; small-molecule inhibitors of KDMs are in the clinical pipeline for the treatment of human cancer. Yet, mechanistic insights into the functional heterogeneity of human KDMs are limited, necessitating the development of chemical probes for precision targeting.

SMARCA4-deficient non small cell lung cancer (SMARCA4-dNSCLC) has recently garnered increasing attention due to its high malignancy and poor prognosis. The literature suggests that in non small cell lung cancer (NSCLC), the loss of SMARCA4 frequently co-occurs with mutations in KRAS, KEAP1, and STK11 rather than in EGFR, ALK, and ROS1. Herein, we present the first documented case of SMARCA4-dNSCLC accompanied with rare mutations of EGFR exon 20 S768I and exon 18 G719X.
